The seat has remained vacant since Scott Driscoll resigned from parliament in November, after an adverse finding from the Parliamentary Ethics committee.

The residual LNP anger from Mr Driscoll's actions while in parliament was predicted to hand Labor its eighth Queensland parliamentary seat, despite the government holding a 10.1 per cent margin.

But a ReachTEL poll, commissioned by the union led Working for Queenslanders last month, found a number of voters in the 35 to 50 year old age group were looking outside the major parties for somewhere to place their vote.

In previously unpublished results from the December 13/14 poll of 774 residents, undecided voters had a 40.8 per cent leaning towards the LNP, a 12.5 per cent leaning towards Labor, while 16.8 per cent mulled over The Greens.

A further 10.9 per cent were considering Katter's Australian Party and 6.6 per cent were attracted by Palmer's United Party, with the rest leaning towards an independent.

The 35-50 year old age group were also the most opposed to the privatisation of health services - 75.7 per cent claiming it would be a "major influence" on their vote, while 15.4 per cent declared it would have little impact and 8.9 per cent indicated they were in favour.

The Together Union's Alex Scott, who has been vocal against the privatisation of health services, said there was a "deep level of concern" within the Redcliffe community about their hospital and Queensland Health in general.

And that would matter at the ballot.

"We are also seeing while there is opposition across the board to privatisation, there is still a great level of cynicism about both the major parties," he said.

"There seems to be a significantly high level of voters who are looking for somewhere else to vote - and that group will have to decide where to place their vote come election day.".

The Katter party has given no indication of whether it will run a candiate, while The Greens have announced John Marshall.

Talosaga McMahon, Len Thomas and Gabriel Buckley will run as independents, while former federal MP Yvette D'ath has been selected for Labor.

Former Family First candidate Kerri-Anne Dooley is the LNP pick.

Queensland leader of the Palmer United Party, Gaven MP Alex Douglas, said his party would only run a candidate if it was guaranteed to win.

Federal leader Clive Palmer appeared to rule out running a candidate on Sunday, but Dr Douglas said the party was preparing polling information on the seat before it ultimately decided.

"Labor's vote has started to fall, it is not secret the were well ahead in the polling initially," Dr Douglas said.

"That's falling now. Why the Labor party is trying to place Yvette D'ath back on the state scene post the new Labor era in the new allegedly non-factional era is hard to understand."

Dr Douglas said his polling showed the LNP was in "graveyard" territory and suggested they withdraw Ms Dooley's candidacy "and avoid utter humiliation".

"As I have said before, if I announce a candiate in Redcliffe, then you know that I believe the PUP are odds on to win that," he said.

"That said, Len Thomas seems to be the stand out candiate to me, at present and I think he will win if we don't run a candiate."

The Redcliffe byelection is expected to be called for February 15, the Saturday after the first week of parliament finishes.
